How do I wind a carriage clock?

Most of these mechanical clocks require a key inserted into winding arbors located on the underside or back plate of the movement. Turn the key gently until resistance indicates the mainspring is fully tensioned. Take care not to overwind the springs, as this can cause damage to the internal gear train. Different trains control the timekeeping, striking, and alarm functions independently.

Why do some carriage clocks repeat?

The repeating function allows the owner to hear the current time chimed in the dark by pressing a button on the top of the case. This mechanical feature was particularly useful during the nineteenth century before bedside electric lighting. Advanced models repeat both hours and quarters using nested gongs or bells. Simpler versions lack this mechanism entirely and only show the time visually.

What is a petite-sonnerie movement?

A petite-sonnerie is a striking train that automatically chimes the hours and the current quarter-hours as time progresses. It represents a high level of nineteenth-century horological skill. These complicated pieces often work alongside alarm functions and repeating levers. They require careful handling and professional servicing to maintain accurate synchronization.
